Abstract
A coolant emulsion liquid blowing remover for cold rolled band steel can be used at the outlet of the frame of various cold-rolled band product. Two upper compressed air hoses (5), which are apart the frame gradually from a string of central line to the edge of a rolling mill, are arranged on the upper part of a band steel (2). The high pressure draught (3) spurted out of a nozzle (4) are symmetrically distributed on the compressed air hoses (5) and it blows through the band steel (2) from the middle part to the edge part against the rolling direction, in which way the coolant emulsion liquid are blew out of the band steel (2). A compressed air hose (6) is equipped at the lower part of the band steel (2), on which the nozzle (4) arranged spurts out the high pressure draught (3) for blowing down the residual coolant emulsion liquid on the undersurface of the band steel (2). The coolant emulsion liquid blowing remover for cold rolled band steel has a simple structure, a convenient maintenance and a favorable effect of blowing and cleaning.
Description
The utility model relates to a kind of cold-strip steel emulsion blow device, belongs to cold rolling finished product band plate face cleaning device, can be used for various cold-strip finished frame outlets.
Cold-strip steel emulsion blow device of the prior art as shown in Figure 3, Figure 4.In cold-strip steel finished frame outlet, rolled on the rack gear 5 that band steel 2 upper and lowers and working roll 1 axis be arranged in parallel, four compressed-air atomizers 4 to the inclination of frame direction respectively are installed.Rack gear 5 drives nozzle 4 clutches according to the width of band steel 2, regulates the distance between the nozzle 4, and air-flow 3 contrary rolling directions blow to band steel 2 upper and lower surfaces, and the emulsion on it is purged.Existing weak point is: the tooth bar drive mechanism is comparatively complicated, needs periodic maintenance.Nozzle has only 4, and emulsion purges unclean, particularly is with the steel plate face width, and is even more serious when mill speed is low, causes the band steel to produce the emulsion spot after annealing, and when the resting period is longer in the storehouse behind milling train, produces corrosion, influenced the quality of product.
The purpose of this utility model provide a kind of simple in structure, easy to maintenance, purge effective cold-strip steel emulsion blow device, to improve the product quality of finished strip
The purpose of this utility model is achieved in that in the horizontal plane parallel with the working roll axis of band steel top, arranged in a crossed manner have two by rolling centerline to limit portion gradually away from frame, become the last compressed air hose of α=5 °～30 ° of angles with the working roll axis.The projection of compressed air hose in the vertical plane of working roll axis place on two, its length is more than or equal to the working roll barrel length, and the centre overlaps, and entire belt steel upper surface is purged guaranteeing.Go up the compressed air hose bottom for every, become β=10 °～45 ° of angles that the nozzle of even layout is installed obliquely to frame direction, strip edge portion with its axis place vertical plane, the contrary rolling direction of the high pressure draught of ejection blows to limit portion by band steel middle part, and the emulsion of its upper surface is purged out the band steel.Band steel below is provided with the compressed air pipe of a, length parallel with the working roll axis more than or equal to the working roll barrel length.Compressed air pipe top becomes γ=0 °～30 ° angle to the frame direction nozzle of even layout to be installed obliquely with its axis place vertical plane, the contrary rolling direction of the high pressure draught of ejection blows to band steel lower surface, and emulsion remaining on it is blown off.Distance between the nozzle on the upper and lower compressed air hose is 50～300 millimeters.
The advantage that the utility model is compared with prior art had is: simple in structure, easy to maintenance, purge effectively, and all the emulsion on its upper and lower surface all can be purged totally with steel width, improve the product quality of finished strip.

Below in conjunction with accompanying drawing embodiment of the present utility model is discussed in detail.
As shown in Figure 1, 2, the utility model cold-strip steel emulsion blow device mainly is made of last compressed air hose 5, compressed air pipe 6 and nozzle 4, is installed in the outlet of cold-strip steel finished frame.In the horizontal plane parallel of band steel 2 tops with working roll 1 axis, arranged in a crossed manner have two by rolling centerline to limit portion gradually away from frame, with working roll 1 yoke be provided with two by rolling centerline to limit portion gradually away from frame, become the last compressed air hose 5 of α=20 ° angle with working roll 1 axis.The projection of compressed air hose 5 in working roll 1 axis place vertical plane on two, its length equates that with working roll 1 barrel length the centre overlaps, and entire belt steel 2 surfaces is purged guaranteeing.Go up compressed air hose 5 bottoms for every, become β=30 ° angle that the nozzle 4 of even layout is installed obliquely to frame direction, band steel 2 limit portions with its axis place vertical plane.Band steel 2 belows are provided with a compressed air pipe 6 parallel with working roll 1 axis, that length equates with working roll 1 barrel length.Compressed air pipe 6 tops become γ=5 ° angle that the nozzle 4 of even layout is installed obliquely to the frame direction with its axis place vertical plane.Distance between the nozzle 4 on the upper and lower compressed air hose 5,6 is 200 millimeters.Upper and lower compressed air hose 5,6 is that the compressed air source of 0.6MPa is connected the nozzle 4 formation high pressure draughts 3 of compressed air on upper and lower compressed air hose 5,6 with on-the-spot pressure directly.One electric heater 8 is housed on the blowpipe line 7 of upper and lower compressed air hose 5,6, compressed-air actuated temperature is heated to 150 ℃.
During work, the high pressure draught 3 of nozzle 4 ejections on the two last compressed air hoses 5 arranged in a crossed manner, contrary rolling direction blows to limit portion by band steel 2 middle parts, and entire belt steel 2 upper surfaces are purged, and the emulsion of its upper surface is all purged out steel band.The high pressure draught 3 contrary rolling directions of nozzle 4 ejections on the compressed air pipe 6 blow to band steel 2 lower surfaces, and emulsion remaining on it is blown off.Because compressed air is through heating, high pressure draught 3 toasts steel band 2 when purging, and with its upper and lower skin drying, more effectively prevents the appearance of emulsion spot and corrosion phenomena.
